Low Noise Block PLL LO 3.85 GHz is a Low Noise Block Downconverter designed for RF signal gain and downconversion from S-band to L-band intermediate frequencies. This PLL LNB amplifies weak 2.0-2.5 GHz signals and converts them to the 1350-1850 MHz range with a highly stable local oscillator, effective ALC system, and extended dynamic range.
This 2.0-2.5 GHz to 1350-1850 MHz LNB features 51 dB gain, noise figure ≤ 2.5 dB, image rejection ≥ 40 dB, and LO stability of ± 1 ppm. A built in front-end Band Pass Filter removes unwanted signals and noise, while a low-pass filter suppresses image channel and local oscillator signals for reliable IF output.

How It Works❓
A Low Noise Block Downconverter first uses a built in front-end Band Pass Filter to remove unwanted signals and noise before the Low Noise Amplifier stage. The LNA strengthens the desired signal relative to the noise floor, and the frequency converter then shifts the input spectrum to an intermediate frequency using a mixer and a 3.85 GHz local oscillator. A low-pass filter suppresses image channel and local oscillator signals, helping maintain clean 1350-1850 MHz IF output.
Why Choose the Low Noise Block PLL LO 3.85 GHz, 2.0-2.5 GHz Input, 51 dB, 1350-1850 MHz Output❓
👉Choose this LNB when you need a 2.0-2.5 GHz to 1350-1850 MHz Low Noise Block Downconverter with 51 dB gain, noise figure ≤ 2.5 dB, image rejection ≥ 40 dB, and PLL LO stability of ± 1 ppm.
